Tsar-Bomb, A602EN, “Ivan”, “Kuzka’s mother” - a thermonuclear device that was being developed in the USSR in 1954-1961 by Russian physisists. It’s started to be called “Kuzka’s mother” after the famous statement of N. Khruschev “we’ll show America Kuzka’s mother!” (that actually means “we’ll make it hot for America” or “we’ll teach America a lesson”) following the events in Cuba and prior to Cuban missile crisis that soon was followed by an explosion of a test thermonuclear bomb.
